General Information
Introduction
The ProAct II driver converts either a 0–200 mA, 4–20 mA, 4–13 mA, 11–20 mA,
PWM, or a 0–5 V control signal from a Woodward electronic control into a
specific actuator position. The driver provides a feedback of 0.5–4.5 V
corresponding to actuator position.
The ProAct II driver comes in two different package configurations: a sealed
aluminum box with conduit fittings for wiring, and a sheet metal box with grommet
holes for wiring. The sealed box is IP56 capable and is designed for skid-
mounted applications. The sheet metal box is designed for skid or control box
mounted applications in an additional enclosure for protection from the elements.
Both units have the same power supply requirements, vibration capability, and
system response.
The ProAct II drivers require a separate electrical supply of 20–32 Vdc. The
supply must be capable of providing a sustained 6 A and a peak 12 A for up to
two seconds for the driver.
The ProAct actuator provides up to 5.4 J (4.0 ft-lbs) transient and 2.7 J (2.0
ft-lbs) steady state of work to move the fuel-setting lever on the engine. The
actuators have position feedback.
Engine stability and response are set by the controlling device, not by the
actuator and driver. Follow the instructions for the controlling device while setting
up the engine control system.
The following configurations are available for the position command input.
